Most popular Agile Interview Questions and Answers
1. What are the differences between Agile and Waterfall model?
Answer: The key differences between Agile and Waterfall model are:
|Agile Model||Waterfall model|
In an agile model, all of the phases like requirement analysis, design, development, testing, and release happens simultaneously in each sprint.
|In waterfall model, work follows a sequential pattern, i.e. the next phase starts only after completion of the previous phase. In a typical SDLC requirement, design, development, testing, and release come one after another.|
|The agile model ensures a faster delivery and completion of a project as customers provide continuous feedback with each sprint that makes any correction fast. Also, it reduces the chance of huge rework at a later phase of the project.||In waterfall model usually customers provide their feedback at later phase of the project which sometimes causes the possibility of huge changes and reworks.|
|Any required changes whether it is requirement or development related is applicable in an agile model.||Waterfall model does not support continuous changes. For example, if requirements are locked down, and any further need of requirement change or a new requirement comes up in the future then it is considered a change request.|
|Agile model is a self-motivated process where the project team runs the overall process in a self-organizing way.||Project managers in a waterfall model control decisions.|
|The agile model ensures less rework. Consequently, it increases the amount of return investment.||Due to late feedback from customers sometimes in a waterfall model project faces a good amount of rework and changes.|
|An agile team means a united team||
In a waterfall model, each phase consists of different team. Hence sometimes it causes coordination issues.
2. What is the basic difference between Scrum and Agile?
Answer: Scrum is a lightweight framework which comes under the umbrella term Agile that consists of principles and values. Agile involves a number of processes, methods, and Scrum is also an approach involved in Agile.
3. What is the difference between an Iteration and a Sprint in Agile?
Answer: Iteration defines a single development cycle in an agile method. It is a common term used for the iterative and incremental development process. On the other hand, the term Sprint is Scrum specific only and defines one development cycle of Scrum.
4. What are the different roles in a Scrum Agile model and their functionalities?
Answer: The different roles and their responsibilities are explained below:
|Product Owner (PO)||
|Scrum Master (SM)||
5. What does story point mean in Scrum?
Answer: It means the total effort required for implementing a backlog.
6. What is a burndown chart in Scrum?
Answer: It is a graphical representation of backlog versus time. In the graphical form, the X-axis represents working days and Y-axis remaining effort.
A burndown chart gives us the impression of the following thing as a whole:
- Work done each iteration
- Remaining work
- Work done so far
- When we can expect the remaining work to be done
7. What is Scrum of Scrum?
Answer: Scrum of Scrum refers to the meeting that happens after the daily Scrum call. The main purpose of this meeting is to coordinate between the teams. Hence, one representative from each team attends the meeting and discuss on the matters like :
- The progress of that particular team since the last meeting
- What is a particular team supposed to do and accomplish before the next meeting?
- The obstacles that a team has faced or facing to complete the task
- If any team is planning to allot some of their work to the following team

8. How do you perform Agile?
Answer: Agile is performed using a process called Scrum. In an agile project, we follow the INVEST strategy for every user stories. Once the agreement is finalized regarding which user stories to begin with, the PM initiates the sprint which is a definite work period for the task.It may last a few weeks to a month. During the sprint execution the team meets in daily scrum call and if necessary in a scrum of scrum to discuss requirements and development progress. These calls also handle any obstacles that the respective teams are facing.
Once a sprint is over the features are verified by the Product Owner for acceptance. The overall process gives the team a scope to learn what has been done best and how to improve the next iteration further. The product backlog is maintained and prioritized by the team for future features and requirements. As the project gets the scope to see the result at the end of each iteration hence business waits less time to see business value.
9. Explain the term INVEST.
Answer: The term INVEST is an acronym which Business analysts and product owner follows to write user stories.
I – Independent – This signifies that a user story should not have any inherent dependency on another user story.
N- Negotiable – A user story is modifiable until they become part of an iteration
V – Valuable – A user story must provide business value to the end user.
E – Estimable – The user story must estimate the size of a user story.
S – Small – User stories should maintain the size that makes it impossible for planning, task, and prioritization feasible with a certain level of certainty.
T- Testable – The user story with its description must implicate the necessary information to make development and testing possible.
10. What are the pros and cons of Agile method?
Answer: Pros and cons of Agile method are as follows:
- The agile method ensures faster delivery as there will be a less waiting period for a working solution.
- The documentation requirements are much less than the waterfall model.
- Agile allows responding quickly in rapidly changing situations.
- Budgeting and accountability is a complex process in agile projects as man-hours are not used in project estimation. It is possible that requirements may pop up during an iteration that may push a future agile sprint.
- Agile put stress on “wait and see” approach which may increase the chances of additional iterations with increased time and cost.
11. What are the 12 Agile principles?
Answer: The twelve manifesto principles of agile development are:
- Customer satisfaction through early and continuous software delivery
- Accommodating changing requirements throughout the development process
- Frequent delivery of working software components
- Collaboration between the stakeholders and developers throughout the project
- Motivate, support and trust the people involved in the project
- Enable face-to-face interactions

- The user stories must be created as a collaborative effort of the scrum team and the product owner.
19. How would you manage a team member who does not like to follow the daily stand up scrum call and consider it as a waste of time?
Answer: A Scrum master should not tolerate and ignore such an attitude. As a rectification measure he can consider below as points of actions:
- One to one discussion with the particular team member to make him/her understand the importance of scrum call. If needed the team member could be assigned further training on the agile method.
- To raise it as an issue through other team members and provide him necessary support to make him understand the importance of stand up call.

20. What are the important attributes of an Agile project that you use during estimation?
Answer: There are three main attributes of an agile project team –
- Backlog: List of activities “to do” for a delivery team which includes design, development, build and testing.
- Cost: Iteration based cost of a team.
- Velocity: In an agile world velocity defines distance over time. Here distance means the size of the backlog and time means iteration length.
Velocity = Story points * Team capacity
21. What is the difference between story points vs. hours from estimation point of view?
Answer: A story point is an abstract measure of effort that is required to implement a user story. Story points along with the sprint velocities provide an estimated approach over the next upcoming sprints. It is a high-level estimation and does not provide actual man hours that are needed to complete the task.
On the contrary, hours based estimation represents actual effort in man hours. It is a low-level estimation.
22. What are some of the advantages of using story points in Agile project estimation?
- Story points make it compulsory to use velocity as a team’s performance data for release planning.
- Story points remove the need for frequent re-estimation. Works like a size-based estimate
- Using points and velocity story points make planning real. It is performance based.
- Less stress inside a team as there is no fixed commitment of days. Hence better and rational performance of the team.
- More collaboration in team’s behaviour.
- Involves different teams during estimation. Hence, story points encourage the cross-functional behaviour.
23. Name some of the popular Agile estimation tools and techniques.
Answer: Some of the popular Agile estimation tools are techniques are:
- Story points
- Poker estimation
- Elative sizing
24. What are the project management tools we use in an Agile project?
Answer: Some of the new breeds of PM tools commonly used in the Agile project are –
- Rally Software
- Version One

25. Explain “Iteration zero” considering its difference from planning activities in a waterfall model.
Answer: “Iteration zero “implies to a time-boxed period at the beginning of a project or release phase when the agile team prepares and plans for the upcoming series of iterations. Activities which may include in “iteration zero” could be
- initial backlog
- making initial architectural decisions
- creating the initial release plan
- Setting up development and testing environments.
Unlike waterfall model planning activities during iteration zero –
- Agile teams work as a single team and don’t wait until complete analysis, design, and planning by the experts before engaging the rest of the team
- Agile teams time-box themselves to limit iteration duration
- Agile teams maintain flexibility and keep the velocity at the high level
- Agile teams plan to revisit and revise their plans, rather than to re-plan on an interruptive basis
